THE CLASSICAL PERIOD (1775-1825). The Baroque period culminated in the masterpieces of J.S. Bach and G.F. Handel. In the middle of the eighteenth century, contemporaneous with the mature years of Bach and Handel, a new musical style developed that is known as Rococo or preclassical style.he music of the Classical era is characterized by objectivity. While emotion is an important aspect of all music, in the Classical period, emotions were carefully controlled. This control is evident in the use of dynamics and expressive differences within sections or movements of a composition.
The same thing happens to a rock when it is heated enough. Of course, it takes a lot of heat to melt a rock. The high temperatures required are generally found only deep within the earth. The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper.
The rising hot rock comes in contact with cold rocks near the surface of Earth where it gives off its heat, cools, and sinks again. Most of the rock in the mantle moves in this broad cyclic flow, indicated by the arrows in the figure.This zone, where rock is soft enough to flow, is called the asthenosphere. (This means of heat transport--the cyclical movement of hot and cold material--is called convection.You can see an example of this in your kitchen by heating a pan of water to what is called a rolling boil: hot water from the bottom of the pan rises up the sides, flows to the center, and sinks to the bottom again.).he rising hot rock comes in contact with cold rocks near the surface of Earth where it gives off its heat, cools, and sinks again.
